As part of the transition journey to Adobe Experience Manager (AEM) as a Cloud Service, you need to move users and groups from your existing AEM system to AEM as a Cloud Service. This is done by the Content Transfer Tool.
A major change to AEM as a Cloud Service is the fully integrated use of Adobe IDs for accessing the author tier. This requires use of the Adobe Admin Console for managing users and user groups. The user-profile information is centralized in the Adobe Identity Management System (IMS) that provides single-sign-on across all Adobe cloud applications. For more details, refer to Identity Management. Because of this change, existing users and groups need to be mapped to their IMS IDs to avoid duplicate users and groups on the Cloud Service author instance.
The Content Transfer Tool (without User Mapping) will migrate any users and groups associated with the content being migrated. The User Mapping Tool is a part of Content Transfer Tool, and its sole purpose is to modify the users and groups so that they can be recognized correctly by IMS, the single-sign-on functionality used by AEM as a Cloud Service. Once these modifications are done, the Content Transfer Tool migrates the specified content’s users and groups as usual.
Once you have learned what a User Mapping tool is, you are now ready to review important considerations and exceptional cases before using the User Mapping Tool. See Important Considerations for User Mapping Tool for more details.
